Using Taylor reagents, my pool water pH tests at 7.8. My tap water is also 7.8. I always assumed tap water would have a neutral pH of 7 or at least very close. What do you guys get for tap water pH?

My tap water is close to 7.8 as well. I think it has a lot to do with the source of the water and the processing that is done. Some on this forum have tap water close to 7.4 but I don't believe I have every seen anyone with lower than that.
Most tap water is treated with chlorine and ammonia for sanitation. If tested with OTO it will show a total chlorine content that is mostly chloramines. These will raise the pH somewhat.
Mine always at 7.8 also - and 1-2ppm of chlorine
Mine is 7.2 with a .5 TC.
Alk is >300 :(
Just tested some more...
CC 2.2
FC 0.6
Why does tap water have more chloramines than the pool? Where does all the combined chlorine in the pool disappear to?
My tap water is FC: 0, TC: 0, pH: 8.2, Alk: 70, Cal: 100
Many municipalities add ammonia with the chlorine used to sanitize water to prevent the formaton of trihalomethans like chloroform, which are suspected carcinogenics. This addition of ammonia favors the formation of monochloramine. When you shock your pool you destroy the choramines.Quote:

You got me interested so I tested my tap water. Rural water system
TC 0
Ph 6.8 or lower since it was a lighter color than the 6.8 reading
So my tap water is low Ph and has no chlorine? That may be good since my pool Ph is always high (SWG)
